Together, you and your treatment team can discuss your kidney cancer treatment options. The best approach for you may depend on a number of factors, including your general health, the kind of kidney cancer you have, whether the cancer has spread and your preferences for treatment.
Surgery is the main treatment for the majority of kidney cancers, with the goal of removing the tumor and preserving normal kidney function. Surgical procedures used to treat kidney cancer may include:
- Removing the affected kidney (nephrectomy). A complete (radical) nephrectomy involves removing the entire kidney, a border of healthy tissue and occasionally additional nearby tissues such as the lymph nodes, adrenal gland or other structures. The surgeon may perform a nephrectomy through a single incision in the abdomen or side (open nephrectomy) or through a series of small incisions in the abdomen (laparoscopic or robotic-assisted laparoscopic nephrectomy).
- Removing the tumor from the kidney (partial nephrectomy). Also called kidney-sparing or nephron-sparing surgery, the surgeon removes the tumor and a small margin of healthy tissue that surrounds it rather than the entire kidney. It can be done as an open procedure, or laparoscopically or with robotic assistance. Kidney-sparing surgery is a common treatment for small kidney cancers and it may be an option if you have only one kidney. When possible, kidney-sparing surgery is generally preferred over a complete nephrectomy to preserve kidney function and reduce the risk of later complications, such as kidney disease and the need for dialysis.
The type of surgery your doctor recommends will be based on your cancer and its stage, as well as your health. Surgery carries a risk of bleeding and infection.
When the cancer is confined to the kidney, surgery is usually the only treatment needed — no drugs or radiation are necessary. Routine follow-up is all that's needed.
For some people, alternative options are available to destroy small tumors without surgery. These options include:
- Treatment to freeze cancer cells (cryoablation). During cryoablation, a special hollow needle is inserted through your skin and into the kidney tumor using ultrasound or other image guidance. Cold gas in the needle is used to cool down or freeze the cancer cells.
- Treatment to heat cancer cells (radiofrequency ablation). During radiofrequency ablation, a special probe is inserted through your skin and into the kidney tumor using ultrasound or other imaging to guide placement of the probe. An electrical current is run through the needle and into the cancer cells, causing the cells to heat up or burn.
These procedures may have advantages for certain patients and are a potential option for people who can't have other surgical procedures and those with small kidney tumors.
Treatments for advanced and recurrent kidney cancer
Kidney cancer that recurs and kidney cancer that spreads to other parts of the body may not be curable, but may be controlled with treatment. In these situations, treatments may include:
- Surgery to remove as much of the kidney tumor as possible. Even when surgery can't remove all of your cancer, in some cases it may be helpful to remove as much of the cancer as possible. Surgery may also be used to remove cancer that has spread to another area of the body.
- Drugs that use your immune system to fight cancer (biological therapy). Biological therapy (immunotherapy) uses your body's immune system to fight cancer. Drugs in this category include interferon and aldesleukin (Proleukin), which are synthetic versions of chemicals made in your body. Nivolumab (Opdivo) is an immunotherapy sometimes used to treat advanced renal cell carcinoma.
- Targeted therapy. Targeted treatments block specific abnormal signals present in kidney cancer cells that allow them to multiply. These drugs show promise in treating kidney cancer that has spread to other areas of the body. The targeted drugs cabozantinib (CaboMetyx), axitinib (Inlyta), bevacizumab (Avastin), pazopanib (Votrient), sorafenib (Nexavar) and sunitinib (Sutent) block signals that play a role in the growth of blood vessels that nourish cancer cells and allow them to spread. Temsirolimus (Torisel) and everolimus (Afinitor) are targeted drugs that block a signal that allows cancer cells to grow and survive. Researchers continue to study how patients with specific genes might respond to certain targeted therapies.
- Radiation therapy. Radiation therapy uses high-powered energy beams, such as X-rays, to kill cancer cells. Radiation therapy is sometimes used to control or reduce symptoms of kidney cancer that has spread to other areas of the body, such as the bones and brain.
- Clinical trials. Depending on your type of tumor, cancer stage and prognosis, your doctor may inform you of relevant clinical research trials. Some clinical trials assess the safety and effectiveness of potential treatments. Other clinical trials try to find new ways to prevent or detect disease.
Be sure to thoroughly discuss with your doctor the benefits, risks and possible side effects of any treatment that you're considering.
No complementary or alternative therapies have been proved to successfully treat kidney cancer. But people with kidney cancer often experience significant stress after diagnosis and during treatment. You may feel sad or anxious, or find it difficult to sleep, eat or concentrate on your usual activities.
In addition to your treatment plan, ask your health care team about complementary therapies that may help you cope with anxiety and stress, such as relaxation therapy or meditation.
Be sure to discuss any other complementary or alternative therapies that you're considering so you learn as much as possible, including any risks, and how such therapies might impact your treatment plan and health.
